Questions

How do I convert a cron expression from CET to AST?

AST is currently 5 hours behind CET. Subtract 5 hours to the hour field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 CET) becomes 0 4 * * 1-5 in AST.

What is the time difference between CET and AST?

Central European Time is UTC+1 / UTC+2 and Atlantic Time is UTC-4 / UTC-3. Right now aST is currently 5 hours behind CET.

Does daylight saving time affect CET to AST cron conversion?

CET and AST observe daylight saving time, so the difference between CET (UTC+1 / UTC+2) and AST (UTC-4 / UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight CET in AST cron?

Midnight in CET (0 0 * * *) is 0 19 * * * in AST, on the previous day.
